74LVC162244ADL,112

Overview

The Nexperia 74LVC162244ADL,112 is a 16-bit buffer and line driver featuring integrated 30 Ohm series termination resistors and 5 V tolerant inputs/outputs with 3-state capability. It operates within a supply voltage range of 1.2 V to 3.6 V and supports an input voltage up to 5.5 V. The device includes IOFF circuitry for partial power-down protection and Schmitt-trigger action on all data inputs. It provides four independent output enables (1OE, 2OE, 3OE, 4OE) controlling the 3-state outputs. The component is specified for operation from -40 °C to +125 °C.

Feature Summary

• Integrated 30 Ohm series termination resistors for signal integrity
• IOFF circuitry prevents damaging backflow current during partial power-down
• Schmitt-trigger inputs provide tolerance for slower rise and fall times
• Bus hold functionality maintains unused data input states without external pull-up resistors

Applications

• Mixed 3.3 V and 5 V environment translation
• Multibyte flow-through standard pin-out architecture systems
• Partial power-down mode applications requiring backflow prevention

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the ADL designation corresponds to the SSOP48 package which was removed in revision 8 of the datasheet. Confirm the active status directly with Nexperia or authorized distributors, as older package variants may be discontinued. Ensure the design accounts for the specific thermal derating characteristics associated with the selected package version.

Selection Notes

Select this component when designing systems requiring 16-bit buffering with integrated termination to reduce external components. The 5 V tolerance allows direct interfacing with legacy 5 V logic while operating at lower voltages like 3.3 V or 1.8 V. Consider the IOFF feature if the system requires safe operation during power-down states. Verify that the SSOP48 package availability aligns with current manufacturing revisions.

Part Context

This part belongs to the 74LVC162244A family of 16-bit buffers and line drivers. The family includes variants such as the ADGG (TSSOP48) and ADGV (TVSOP48). The ADL variant specifically denotes the SSOP48 package configuration. All variants share identical electrical characteristics and functional descriptions, differing only in physical packaging dimensions and lead configurations.

Replacement Considerations

Public confirmed substitute part numbers include 74LVC162244ADGG and 74LVC162244ADGV. These alternatives offer the same electrical specifications but utilize TSSOP48 and TVSOP48 packages respectively. Designers must verify footprint compatibility and reflow soldering profiles when substituting these package variants.
